Gadolinium-enhanced three-dimensional MR angiography in jugular phlebectasia and aneurysm

True jugular vein aneurysms and phlebectasias are very rare abnormalities, which are usually discovered in children. Though their ultrasonographic fea tures have been well described, magnetic resonance angiographic appearance of these lesions has not been reported in the radiology literature. We desc ribe gadolinium-enhanced MR angiographic findings in two patients with inte rnal jugular vein phlebectasia and one patient with anterior jugular vein a neurysm. The jugular venous system and its abnormalities were successfully depicted in the coronal plane, much like the images of coronal angiography. (C) 2001 Elsevier Science Inc. All rights reserved.
